I have a Roku Streaming Stick 3800X bought in 2018 connected to a Samsung UN50MU630D Smart TV. Also connected to the Samsung is a DirecTV Genie HR54/500 and Panasonic SA-BTT404 BluRay Home Theater system.
Until a couple days ago I was able to control the sound of the Home Theater with the Roku remote, in fact the problem is actually worse. I cannot control the sound of the Home Theater with the Samsung Remote either when I was able to do this before.
How do I set up the Roku Remote to control the sound of the home theater? Maybe this will help me remember to get the whole thing working again.
